Toilets occasionally back up; that's just something that can happen randomly. However, if the issue happens too often, it's time to call in toilet backup repair services. Problems can occur anywhere along the line, from right where materials go into the drain to the city sewer lines at the street. Many issues, however, happen right at the base of your toilet, and a repair service is the best candidate for removing those problems quickly.
Did Someone Put Food Down the Toilet?
One thing that's become more common in larger houses is having renters who use little kitchenettes near their rooms. The bathroom sink often serves as the dishwasher site for these tenants. Many people know not to put food down a bathroom sink drain as there's no disposal, but they don't realize that they can't put food down the toilet, either. The food can catch on the flange and block the drain, and floss, too, can catch on the flange or seal and become tangled up in whatever gets flushed down after it. All food, even small bits, should go in the trash or a compost bin, and not down the toilet.
Damaged Internal Parts
One of the types of backups that can happen with toilets is too much toilet paper. These are generally easy to clear; if the toilet backs up, wait a while and flush again after the water has had a chance to make more of the paper dissolve. However, that solution may not work if there are damaged parts (e.g., flanges or seals) in the damaged drains, especially if they're catching most of the toilet paper. The paper will still eventually dissolve, but it will take longer as part of the drain may be blocked by the damaged part. The portion of paper right over the part of the drain that's still open may not have dissolved yet when you first try flushing after waiting.
Partial Clogs of Gunk
This possibility is similar to something that can happen in sink drains, but in a toilet, it just seems so much worse. There may be a buildup of gunk—biofilm, other materials—along the sides of the drain pipe leading out of the toilet. That would narrow the pipe so that smaller amounts of toilet paper and other material could cause a clog and a backup. The easiest way to take care of that buildup for sure is to get a repair service. Yes, there are liquids that you can try to pour down the toilet yourself, but a repair service can physically remove the gunk and get the pipes flowing again very quickly.
